: the city-of New York, county of New York, and State .of-New York, andat the borough of Manhattan, in the city'of New York ,v county of NewYork, and State of New York, have invented a new and useful Improvementin Water-Closet Apparatus, of which the following is a specification.

"--'This,.invention relates to water closets andit consists of certainnovel parts and combinations of parts particularly pointed out in theclaims concluding this specification.

l In the accompanying drawings wherein we have shown ;a preerred'embodiment of our invention by 'fway of illustrationyFigure 1 is aperspective view of a I 4 bowl involving our invention; Fig. 2 is'aperspective aw looking into the bowl from the rear; Fig. 3 .is asecviewof one of the hinged posts for the seat,

'Fig. 4 is a sectional view of a modified form of our in- .fvention;Fig. 5 shows a central cross section of the channel connecting thesupply pipe with the flush rims. The following is a' description of thewater closet 2,5 bowl shown in the drawings, which illustrate formswhichfwe at present prefer to embody our invention, but it be understoodthat various modifications and changes may :be made in the detail's'ofthe same without departing from the spirit of our invention and withoutexceeding the scope of the concluding claims.

Referring to Figs. 1, 2, 3 and 5 of the drawings, the numeral 1represents a water closet bowl provided with the flushing rims 6 6.These two rims connect with a common source of supply by means of thechan- They then lead around leaving'aagecess or space 3 between theirends, the walls of this recess being the surface of the bowl and theopposed erids of the flush rim. The upper surface of the 4 flush rim israised above this recess and extended to from a shield 2 over the same.The ends of the flush rim have perforations 7 7 therein whereby thesurface of the bowl in-the recess maybe flushed, At the rear of thebowl, also, the ends of the flush rims are opposed toeach other and 'a'recess or space 5 is here formed, the

7 walls of said recess being the ends of the rims and the rear surfaceof the bowl. The upper surface of the flush at this point is preferablyraised above the general co1it o ur of the and forms a shelf, the top ofwhich -extends inward to the line of the flush rims and outward beyondthe back of the bowl. The surfaceof the recess beneath this plate isflushed by means of the per-' I forations 8, 8, in the opposed ends ofthe flush The numeral 10 indicates the seat which hasithe frontSpecification of Letters Patent.

cutaway and the ends thereof formed to fit each side of the shield 2,which shield preferably projects slightly beyond the front of the bowlso as to meet the forward ends of the seat and impart to the structure asymmet- The seat at the rear has a dove-tail block 11 inlaid to preventthe section from parting.

The numerals 12, 12, indicate hinged posts each having a tubular sectionextending to the rear. These posts are secured to the rear-of the shelf4 by a nut 20 or other'means. 4

13 is a rod extending through the hinged posts and to which the seathinges, 14, 14 are secured by means of nuts 15, 15 which are screwed tothe ends-of the rod '13.

16 is a washer of any suitable substance within the rearwardly extendingsection of the hinged posts 12. This washer serves as a lock to checkthe movement of the rod 13, against the surface of which it is forced bymeans of the spring 18 and the screw plug 19. Thus surface is inclinedtoward the wall of the bowl.

be necessary to so clean it, unless the same is done manually. With ourinvention, it will be plainly'seen' that this difliculty has beenovercome, for, by dividing the flush rim a recess is left at the frontand at the rear between the ends of the rims where any substance ofperforations in the rims. Hence, all the surface within the bowlnecessary to be cleaned will be flushed.

Furthen'it will be noted, as we have previously stated in thisspecification, that the upper surface of .the flush rim at the front ofthe bowl is raised above the recess and extended to form a shield 2 overthe same, and also that at the rear of the bowl theends of the flushrims are opposed to each other and a recess or space 5 formed, the wallsof said recess being the end of the rims and the rear surface of thebowl. Further, the upper surface of. the flush rim at this point, or therear, is also raised or elevated above the general contour of ,the rim.It will therefore be noted that We have provided a bowl having a frontelevated portion might collect, and theserecessesare flushed by meansformed with a recess and arear elevated portion formed with a recess,and that the entire bowl, includingv the main portion of the bowl, andthe front and'rear elevated recess, maybe thoroughly flushed. Therefore,any substance, instead of collecting upon the rim at the front and rearof the bowl, will lodge in the 'recess from whence it is readilyremovable by means of the flush.

What we claim is;

l. A; water closet howl having a flushing rim, a shield formed 011 thetop and front of the bowl integral with the rim and having the sideswithin the bowl cut away to form a recess. a flushing rim terminatingnteach sidoof the recess and havim, an outletat either end discharginginto the recess to clean the wall of said recess. and a seat having thefront cut away to conform to the sides of the shield.
